WARN: Unable to register shutdown hook due to JVM state

[amshf <si...@yahoo.com>]

I'm using Camel to route Activemq messages. Camel is boot with
org.apache.camel.Main class like this:




*problem:* when I send Ctrl+C to shutdown the camel, it logs this warning:



Why? and how to fix this?

Hi

I guess your problem has nothing to do with the shutdown hook of Camel
itself but with another hook log4j tries to setup as well:  

https://github.com/apache/logging-log4j2/blob/trunk/log4j-core/src/main/java/org/apache/logging/log4j/core/LoggerContext.java#L208

Maybe verify that the Camel / slf4j / log4j versions you make use of are
properly matching.
